I have some application settings (like database configuration etc.) stored in app.config file. As it is a standard .Net approach i haven't expected any troubles with this and installer. I would like to make the newest version of the program available to the users via wix installer, but I couldn't find a simple way of updating the .config file without trashing the old settings values. The perfect solution for me would be a way to merge somehow the old file with the new one.
I am thinking about several possible approaches (don't know if all are possible) 1. Compare and merge old and new .config files using Custom Action A problem with this one is I can't get to access the new file (the one that's gona be installed) 2. Backup old file using Custom Action and merge the backup with the freshly installed version using another (deferred) Custom Action 3. Instead of copying the .config file from source move creating it to the wix (using XmlConfig or XmlFile tag) Don't know how to write conditional set/create values - is it possible? 4. There is some other obvious way, which I can not see maybe? So in Your opinion what is the best approach for updating the .config file during the update/upgrade? Would moving some values from app.config to registry be better? -- View this message in context: http://n2.nabble.com/Updating-app.config-tp1077780p1077780.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
